Abstract

Land degradation in Ethiopia is a pressing issue that demands immediate attention. Although various sustainable land management options have been introduced through top-down approaches, farmers have shown low adoption rates. The objective of this research was to assess the community prioritization of landscape restoration technologies and the appropriation of ecosystem services in the Basona-Worena and Doyo-Gena woredas of Ethiopia. The evaluation of land management option tool was used to survey farmers' preferences and compare different land management options based on input, cost, perceived advantages, and potential drawbacks.Data from 64 participants revealed that farmers were interested in a wide range of benefits. However, their top three preferences were increased food supply, enhanced soil fertility, and improved water supply. The study emphasized the need for site-specific land management measures. Farmers in Basona-Worena favored terrace and bund practices, while farmers in Doyo-Gena preferred exclosure and agroforestry practices. Conversely, the propensity of terracing to attract rodents and pests, the lengthy time takes to see results from bunding, and the cost of gabions were among the shortcomings that farmers identify in conservation techniques. Terracing was the first option for supplying fundamental ecosystem services in both locations, followed by biological measures, water percolation pits, and bunds. All farmers ranked the business-as-usual option as their least preferred option because they perceived it to have limited potential for yielding desired benefits. These findings provide a robust model for informed decision-making on suitable restoration technologies, holding promise for landscape restoration initiatives in Ethiopia and similar locations worldwide.

Abstract

Bantul Regency, located on Java Island, is one of the areas in Indonesia with abundant groundwater sources, thus experiencing rapid urban growth. The hazard of groundwater vulnerability in this area has increased due to urban expansion that coevals with changes in land use and human population growth. The objective of this study was to analyze how groundwater vulnerability has changed due to land use conditions and what impact those changes have had. Because of the various variables associated with urban growth, the sub-districts of Bantul and Bambanglipuro were explicitly chosen as research areas. This study compared groundwater vulnerability and land use between 2009 and 2021 in a spatiotemporal manner. The vulnerability determination method used is the Susceptibility Index (SI), which consists of the parameters depth of groundwater table, groundwater recharge, aquifer media, topography, and land use. Each parameter is processed into an index of groundwater vulnerability by scoring and weighting methods. Techniques for descriptive comparative analysis are employed to ascertain how changes in land use will affect the degree of groundwater vulnerability. The results of the land use classification show that the agroforestry area has decreased while the semi-urban area has increased in 2009 and 2021. The sub-district of Bambanglipuro underwent numerous changes. On the other hand, it is known that medium and high vulnerability levels dominate groundwater vulnerability. In this instance, it is concluded that variations in land use have impacted how groundwater vulnerability levels are distributed.

Abstract

The frequency ratio (FR) model is employed for the landslide susceptibility analysis of Iruvazhinji watershed of Chaliyar river basin, central Kerala. For the present study, slope, slope aspect, slope curvature, elevation, Slope Forming Material (SFM), drainage density, distance from river, Topographic Wetness Index (TWI), Land Use/Land Cover (LULC), and Normalised Vegetation Index (NDVI) have been considered as landslide causative factors. The spatial relationship between these factors and landslide occurrences in the study area was examined, and the results showed that SFM, elevation, and slope angle have a significant control over landslide occurrence. Using the FR algorithm, we generated a Landslide Susceptibility Map (LSM) and zonal categorization of the study area into low, moderate, high, and very high susceptibility zones. Most of these areas are classified as either high or very high susceptibility zones, reflecting a higher potential for landsliding in the study area. The validation of the susceptibility map was carried out via calculation of the Area Under the Curve (AUC) of Receiver Operating Characteristic (ROC) analysis, which points to a high level of landslide susceptibility model accuracy. The findings of this study help in land use planning, hazard mitigation, and disaster risk in vulnerable landslides, as well as support in improving resistance measures against disaster management due to landslides.

Abstract

Erosion and sedimentation resulting from land use changes can negatively impact watershed quality and threaten sustainability. Watershed quality is particularly crucial in areas designated for energy sector development, such as Nuclear Power Plants (NPPs). One potential NPP site in Indonesia is located downstream of the Raya watershed, where high river sedimentation may affect its performance. This study aimed to determine the spatial pattern of mean annual sediment yield in the Raya watershed using hydrological models. Due to the limited availability of data, secondary data analysis was employed, utilizing a geospatial hydrological modeling approach with the Soil and Water Assessment Tool (SWAT). The Hydrological Response Unit (HRU) was used as an analytical unit to identify physio-geographic similarities based on land use, soil type, and slope, which serve as dynamic hydrological controls. The results reveal the hydrological characteristics of the Raya watershed: an elongated shape, a dendritic river network, and moderate drainage density. The average slope is 12.6%, with a clay-loam soil texture and land cover dominated by dryland forests, oil palm plantations, and mining activities. The SWAT model produced an average sediment yield of 251.7 t/ha/year over a 10-year simulation period, classified as high sedimentation. High to very high sedimentation was predominantly found in the upstream areas, moderate sedimentation at the foothills, and low sedimentation in the alluvial plains downstream. These findings indicate a decline in land quality in the Raya watershed, highlighting the need for conservation measures to ensure the sustainability of the watershed ecosystem.

Abstract

Tangerines (Citrus reticulata var. Tejakula) were destroyed in 1984 by CVPD, allegedly because the use of chemicals was too intensive, resulting in land degradation. Since ten years ago, these oranges have been successfully cultivated again using healthy organic cultivation, but farmers have difficulty getting organic fertilizer. This research aimed to identify and isolate the Arbuscular Mycorrhizal Fungi (AMF) on tangerines cv. Tejakula, their colonization of the roots and effect on soil fertility. Exploration was conducted by collecting root and soil samples in tangerine cv. Tejakula production centers are in the Tejakula District, Buleleng Regency. Spore isolation was conducted using wet filtration and centrifugation techniques, while root colonization by AMF was carried out using the staining method with trypan blue. The isolated spores are composited into AMF biofertilizer using volcanic sand as a carrier medium. The biofertilizer was then tested for its effect on soil fertility with three treatment levels of AMF spore doses (0, 20, and 40 spores/50 g of carrier media per plant). The results of exploration, isolation, and identification showed that three genera and six species of AMF were found. The spore density ranged from 17 to 32 per 100 g of soil (mean 24.17 ± 2.02 spores). The average root colonization by AMF was very high, ranging from 90 to 100%, and the application of AMF biofertilizer at a dose of 20 and 40 spores per plant provided soil fertility was much better than the control (0 AMF spores per plant).

Abstract

The wide areas of critical land in Indonesia are attracting a high level of attention due to the significant influence of global warming. Addressing this issue requires several priority efforts, such as critical land rehabilitation programs. The level of critical land rehabilitation can be evaluated with remote sensing technology. Therefore, this research aimed to assess critical land in South Sulawesi rehabilitated by PT Vale Indonesia Tbk (PT VI) as compensation for mining nickel from the forest areas. The assessment was conducted in three villages across Luwu, namely Binturu, Lamasi, and Rante Alang. Successful critical land rehabilitation was determined by monitoring land cover changes (LCC) based on satellite data generated using Harmonized Sentinel-2 from 2019 to 2023. Furthermore, analysis was performed using the Google Earth Engine (GEE) platform with the Random Forest machine learning algorithm and correlation matrix. The result showed five LC classes, including high-density, low-density, shrubs, bare land, and buildings. Before rehabilitation in 2019-2020, non-forested LC in the three villages was only at a proportion of 23.41%, while forested LC reached 58.92% and increased to 80-95% in 2021-2023. Critical land rehabilitation in Luwu was considered a success due to increased LC at high- and low-density classes, along with declines in bareland and buildings. Additionally, an inverse correlation was detected between high- and low-density LC classes and buildings, barelands, and shrubs. Elevation in high- and low-density LC could significantly contribute to mitigating climate change.

Abstract

To access the ecological sustainability and resilience, it is necessary to periodically examine various ecological properties in areas with high pollution and contaminant risks. Kolar Gold Fields (KGF) in Kolar, Karnataka, showcases one amongst the India's most contaminated zones because of the extensive gold mining and their lingering effects. In KGF, quality of ground water has severely reduced as there exist extensive mining tailings, locally referred as cyanide dumps, which have been neglected for several preceding years without proper disposal strategies. The current approach focuses on the water pollution caused by heavy metal deposits in the KGF region. Groundwater samples were  sampled from Oorgam, an abandoned region in KGF, and subsequently filtered for water quality examinations. The investigation  documented concentrations of several metals, including cadmium (0.068 ± 0.0024 ppm), lead (0.288 ± 0.0016 ppm), nickel (0.058 ± 0.0047 ppm), and chromium (0.23 ± 0.0235 ppm) and have met the standard specifications in accordance with World Health Organization (WHO). Prominent pH disparity was documented  amongst the experimental samples, with a detectable  pH drop in the aqua-purified water on comparison  to the positive control. The test results imply that the water samples collected  from KGF remains unpotable for consumption or irrigation due  the persistence of high levels of heavy metals concentration. This study underscores the urgent requisite for remedial approach  to ensure water safety for drinking  and irrigation in the area.

Abstract

Gully erosion can cause significant soil loss; thus, it must be controlled. This study aimed to develop a landscape design for controlling gully erosion in a volcanic environment with a thin soil layer. The primary data used was Unmanned Aerial Vehicle (UAV) data combined with field surveys and in-depth interviews. A collaborative approach was used to develop the landscape design to minimize the impact of gully erosion. The finding showed that gully erosion had entered adult to old age since the scars (incisions) at the gully bottom existed. According to the community, gullies must be controlled, although they do not affect land productivity. Vegetative control is the most favored method of gully erosion control. Local vegetation with the potential for additional value is chosen to control gully erosion. Strengthening community capacity is the most favorable way to manage gullies. Through good understanding, local communities can control the development of gullies. Further strengthening of regulations related to gully erosion control will have a domino effect on land sustainability. This finding can be extrapolated globally to locations with similar land characteristics.

Abstract

In the Koraiyar basin, located within the districts of Tiruchirappalli and Pudukkottai in Tamil Nadu, India, groundwater samples were investigated to evaluate their quality and appropriateness for both drinking and agricultural purposes. Groundwater is a dynamic source for sustaining human life and various activities; however, its overuse and deteriorating quality pose significant challenges. Groundwater faces threats from various factors, including climate change, changes in land use, and population growth, all of which impact both the quantity and quality of available groundwater. Salinity exerts a substantial influence on various parameters, as indicated by the strong correlation between electrical conductivity (EC) and many other factors. It is inferred that pre-monsoon samples exhibit slightly lower quality compared to post-monsoon samples, although they remain suitable for drinking, with only a few exceptions. Most of the samples are safe to drink and use in agriculture because they are within allowable levels. Total dissolved solids (TDS) and total hardness (TH) data show that the groundwater samples are mostly of the pre-monsoon hard to extremely hard type. The Gibbs plot's evaporation zone contains samples, indicating that surface activities like agricultural runoff and other human-induced variables like home sewage dumping can contaminate groundwater. With the exception of samples showing average salinity and high sodium concentrations, all other samples are suitable for irrigation across various soil types.

Abstract

Ultisol is generally characterized by a high clay content in the argillic horizon, easy compaction, slow permeability, and unstable aggregates, resulting in low total porosity. Organic soil amendments such as compost and biochar can be used to improve soil organic matter, aggregate stability, and other physical properties of Ultisol. A field experiment was conducted using a randomized block design to assess the potential effects of Leucaena compost (LC) and coconut shell biochar (CB) on the physical properties of Ultisol and maize yield. The treatments included combinations of compost (0, 5, and 10 t/ha), biochar (0, 5, and 10 t/ha), and inorganic fertilizer (50% and 100% of the recommended dose). The results showed that the application of Leucaena compost and coconut shell biochar improved the physical properties of the soil. Compost and/or biochar applications at 10 t/ha enhanced soil organic matter, total porosity, aggregate formation, aggregate stability, pore size distribution, and reduced soil bulk density, improving maize growth and yield.
